total surface area(TSA)= 462 cm²
TSA=3πr²
462 = 3*22/7*r²
462*7=66r²
3,234=66r²
3,234/66=r²
49=r²
√(49=r
r=7
therefore the radia of the hemisphere is 7
now,
volume of hemisphere(V) = (2/3)πr²
V=(2/3)*(22/7)*7²
V=44*7
V=308

which two circles below are congruent? explain your reasoning
Answer:
The first one to the left and the third one.
Step-by-step explanation:
As long as two circles have the same radius/diameter, they are congruent.
Circle 1 has a radius of 22.5.
Circle 2 has a radius of 22.
Circle 3 has a radius of 45/2 = 22.5. (Diameter/2 = radius)
Therefore, Circle 1 and Circle 3 are congruent.

19. The marked price of a certain handbag is $400. After two successive
sales, the selling price of the handbag becomes $225. If the discount
per cent in each sale is x%, find the value of x.
Answer:
x = 25%
Step-by-step explanation:
At the first sale of 25% off, the handbag price dropped from $400 to $300. This is because (400 x 0.25 = 100) and (400 - 100 = 300) Therefore, the selling price of the handbag after one sale was $300.
At the second sale of 25% off, the handbag price dropped from $300 to $225. This is because (300 x 0.25 = 75) and (300 - 75 = 225). Therefore, the selling price of the handbag after two sales is $225.
The value of x remained the same for both sales. x = 25% or 0.25

180 in the ratio 1:3:4
Answer:
let 1:3:4 be written as x:3x:4x
therefore, x+3x+4x = 180
8x = 180
x = 180/8
x = 22.5
therefore, x = 22.5
3x = 22.5 * 3 = 67.5
4x = 22.5 * 4 = 90

Answer:

Step-by-step explanation:
You have a cake that is 10 inches in diameter. You expect 12 people to share it, so you cut it into 12 equal slices. Before you get a chance to serve the cake, 12 more people arrive! So, you decide to cut a concentric circle in the cake so that you will have 24 pieces. How far from the center of the cake should the circle cut be made so that all 24 people get the same amount of cake?
Answer:
3.5355 inches
Step-by-step explanation:
Area should be same the concentric circle and rest piece .
let's consider the radius of concentric circle as r
so it's area is π r²
area of whole circle is π (5)" ( because diameter is 10 inches)
so the area of rest piece is π (5)² - π r²
π (5)² - π r² = π r²
5² = 2r²
r² = 25/2
r = √(25/2)
r = 3.5355 inches

Johan's gift shop needs to mail 45 checks to the bank. If they can put 5 checks in each envelope, how many envelopes how does the shop need to use?
Answer: 9 envelopes
Step-by-step explanation:
Divide the 45 checks into 9 groups of 5.
------------------------------------------------------------------------
| 5 | 5 | 5 | 5 | 5 | 5 | 5 | 5 | 5 |
------------------------------------------------------------------------
45 checks divided into 9 envelopes equals 5 checks per envelope
45 ÷ 5 = 9
Take away one group of 5 checks from the 45 checks. Then take away another group of 5 checks, and another, and another. When there are no more checks, count how many groups you took away. You can take 9 groups away from 45, so that is your answer.
To tell that the answer is 9 groups of 5 checks, follow these steps.
Look at the equation. 45 ÷ 5 = 9.
The amount of groups is what 45 ÷ 5 equals. What the 45 checks is divided by is the amount in each group.
This means that there are 9 groups of 5 checks.

Two numbers have a sum of 136 and a difference of 32. Find the smaller of the two numbers.
Answer:
Smaller number = x
Bigger number = x +32
Why? -- the difference of the numbers is 32, this also means that one number is 32 greater than the other.
x + x+32 = 136
2x +32 = 136
2x = 104
x = 104/2
x = 52
----> The smaller number is 52 <-----
We can check by solving for the bigger number.
Bigger number = x+32
x = 52
52 + 32 = 84
Bigger number = 84
Bigger number + Smaller number = 136
84 + 52 = 136
The numbers are 84 and 52 if the two numbers have a sum of 136 and a difference of 32.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
Two numbers have a sum of 136 and a difference of 32
Let x be the first number and y be the second number:
x + y = 136
x - y = 32
After solving the above linear equation by elimination method:
2x = 168
x = 168/2
x = 84
2y = 104
y = 52
Thus, the numbers are 84 and 52 if the two numbers have a sum of 136 and a difference of 32.

Please I beg you help me
Answer:
Option D
Step-by-step explanation:
Going through the choices will help determine which option best simulates the random selection of a voter.
Flip a coin three times, and assign outcomes as follows: HHH, HHT, or HTH = Nava; HTT, THH, or THT = Jensen; TTH = Moretti, TTT = Chang.
Given that it is a random selection of the 4 candidates, it means the probability of choosing either one of them is equivalent. From the option, it can be found that Nava and Jensen have a higher chance of being voted than Moretti and Chang, which would not fit the criteria of being randomly selected.
Roll a number cube, and assign outcomes as follows: 1 or 2 = Nava, 3 or 4 = Jensen, 5 = Moretti, 6 = Chang.
Again, Nava and Jensen have a higher chance of being voted than Moretti and Chang. Therefore, this is not the correct option to simulate random selections of the 4 candidates.
Roll a number cube, and assign outcomes as follows: 1, 2, or 3 = Nava, 4 = Jensen, 5 = Moretti, 6 = Chang.
Nava has a higher chance of being voted, so this option does not fit the stimulation.
Flip a coin twice, and assign outcomes as follows: HH = Nava, HT = Jensen, TH = Moretti, TT = Chang
In this scenario, all 4 candidates have an equal chance of being voted, so this option would best simulate the random selection of a voter from the city.
